5 loaded. One form of such apparatus embodies a car dumper, having a panor other member into which the oarcontents are adapted to be emptied,and from which a discharge chute extends down- Wardly into the loadreceiving vessel. One form 10 of chute, which has been used for thispurpose has embodied a plurality of intertting telescopio tubularmembers, which collectively are arranged g to be inoved universally withreference to the at 13, while a discharge chute 14 is shown as extendingdownwardly from the lower end of the pan. The chute 14 is mounted foruniversal movement with reference to the pan; movement in one planeoccurring about the axis of the hinge pin 15 and in a transverse planeabout the axis of the hinge pin 16. lThe mechanism for eiiecting suchmovement does not form part of this invention and therefore, it is notshown in the drawings.

The present invention is concerned with the provision of means forshifting the discharge chute in a direction tnvmrd mm 9mm, fsm +1 whichis suitably connected by gearing 41 to a drum shaft 42. I then providetwo drums 43 on the shaft and utilize cables 44, which extend from thedrums', and are connected at the ends thereof to the carriage. Thus,when the motor is operated to wind in the cables, the carriage is pulledupwardly and the conduit 20 is contracted. With this arrangement, I mayutilize a motor brake, which if reelased, will allow the carriage todrop by gravity. During such upward and downward movement of thecarriage, the discharge chute may be moved parallel to itself withoutshifting the position of the pan about its pivot 45.

In Figs. 3 and 4, I utilize a reversible motor and I so connect the endsof each cable to the carriage that rotation of the motor in onedirection will pull the carriage upwardly, while rotation in theopposite direction will force the carriage downwardly. To carry out suchplan, the parts-corresponding to those illustrated in Figs. 1 and 2 areidentified by the same reference characters, so that only the modifiedmechanism need be described. Such mechanism comprises sheaves 46, whichare mounted for rotation upon the supporting members 29 and 30 and belowthe extreme limit of downward travel of the rollers 35. The cable isthen wound around the drum a sufficient number of times to avoidslippage, while-the drum is being rotated, and one end l4'1 of eachcable is attached to the carriage at 48,`

while the opposite end 49 after passing around the associated sheave 46,is also attached'to the carriage at'48. Thus it is apparent thatrotation of the motor in a direction to pull upwardly on the cable end47 will draw the carriage upwardly while rotation in the oppositedirection will place the cable 49 under tension, and thereby draw thecarriage downwardly.

A further modification of my invention is illustrated in Figs. 5 and 6wherethe mechanism for actuating the carriage embodies a rack and pinionconnection. Here again, the parts corresponding to those illustrationsin Figs. 1 and 2 will be correspondingly numbered so that only themodified mechanism need be described. Such mechanism comprises pinions50, which are adapted to engage racks 51 on the underside of thecarriage. The pinions in turn are mounted for rotation upon therelatively stationary members 27 and are disposed below the extremelimit of downward travel of the rollers 35. Thus, rotation of the motorin one direction will shift the carriage in one direction, and viceversa.

An important advantage Jf tl .e present invention is the fact thatregardless of the width of the vessel that is to be loaded, the chutedischarge opening may be positioned in close proximity to either side ofthe hull without necessitating an objectionable drop of the materialfrom the chute into the vessel.v Thus, I minimize breakage and assureaccurate distribution of the load without necessitating, unnecessarymanipulation of the pan. Furthermore, anrapparatus embodying myinvention may be readily installed on existing car dumpers withoutnecessitating extensive modifications in the construction thereof.

I claim:A

1. In a car dumper, the combination with a material receiving pan, of amember supported by the pan and movable longitudinally thereof, adischarge chute vpivotally connected to said member, a closed extensibleconnection between the lower end of the pan and the upper end of thechute for providing communication between the pan and chute, and anelectric motor operatively connected to said member for moving it withreference to the pan, whereby the chute may be moved, as a unit, withreference to the pan, while remaining in operative communicationtherewith.

2. In a car dumper, the combination with a material receiving member, ofa discharge chute extensibly connected to said member, a carriagemounted on the member, and pivotally connected to thechute, meansincluding a closed telescopic conduit for connecting the chute andmember, and means for shifting the carriage with reference to themember, whereby the chute may be moved toward and away from the pan,while the axis of the chute is maintained in substantially the sameposition with reference to a vertical.

3. In a car dumper, the combination with a material receiving member, ofa discharge chute extending downwardly therefrom, said chute beingextensibly connected by a closed conduit to the member, a carriagemounted on the member, a cable connected to the carriage and means formoving the cable to raise or lower the carriage, whereby the chute maybe moved with reference to said member, while the axis thereof remainsin substantially the same position with reference to a vertical.

4. In a car dumper, the combination with a supporting frame, of adischarge pan mounted thereon, a carriage supported by the pan, a closeddischarge chute connected to the carriage, means for moving the carriageand chute with reference to the pan, and means forming a continuouspassageway between said pan and chute in all operative positions.

5. In a car dumper, the combination with a material receiving pan, aclosed articulated passageway in communication with the lower end of thepan, and means supported by the pan and movably mounted with referencethereto, said means being connected to the passageway intermediate thepan and the discharge end of the passageway, and means for shifting thepan-supported means with reference to the pan whereby the passageway maybe extended and contracted in a direction extending longitudinally ofthe pan.

6. In a car dumper, the combination with a support, of a pan pivotedthereto, a material'conducting conduity operatively connected to saidpan, said conduit being closed and extensible, and extending in adirection longitudinally of the pan,

and a carriage shiftably mounted externally of thepan and operativelyconnected to the conduit for extending and contracting it with referenceto the pan.

7. In a car dumper the combination with a material receiving pan, of anextensible material conducting conduit connected therewith, a dischargechute depending from said extensible conduit, an electric motor mountedon said pan and mechanism includinga rack and pinion for connecting themotor to said chute, whereby rotation of the motor in either directionmoves the chute toward and away from the pan.

3. In a car dumper, the combination with a pan, of a closed articulatedpassageway connected with the pan and extensible in two directions froma common point on the passageway, a pivotal support forthe common point,and means for moving the pivotal support toward and away from the pan.

9. In a car dumper, the combination with a material receiving pan, of anextensible conduit in a common plane with the pan, said conduittinuation thereof, and a discharge chute pivotally` connected to thehollow member, the extensible conduit cooperating with the elbow, hollowmember and chute to provide a closed articulated and continuous conduit.

11. In a car dumper, the combination of a material receiving pan, anextensible conduit at the lower end of the pan, a carriage supported formovement in a line parallel with the conduit, an articulated elbow atthe lower end of the conduit, said elbow being pivotally supported onthe carriage, and a discharge chute pivotally supported on the elbow,said last-named pivot extending in a direction normal to the first-namepivot.
